Does anyone know how to insulate sash windows without paying over the odds? I tried to get a quote but was quite astonished of the amount. Cheers[/quote]

Hi,

I have just seen your post and i have been looking for similar solutions to insulate windows and i came across "blindseal.co.uk" Their system is designed to be fitted around the edges of a window as a seal for when a roller blind is installed or is going to be installed on a window to seal gaps between the edges of the blind and the wall, therefore improve heat retention in the room, reducing energy bills and preventing draughts. Prices seem quite reasonable. May be worth a look.
